Route 32 from Petersham and Worcester enters from the left (22.7) just before the highway dips into the creek bottom at the edge of the Quabbin basin. Thence it ascends to the New England upland level, where a lookout (25.5) affords an expansive view to the east and north, with Mount Monadnock rising prominently on the distant skyline. New Salem (25.8) is on the hilltop. Hornblende schist outcrops at intervals across the broad ridge, and especially near the descent (28.4) southwestward to another stream (30.3) which empties into the Quabbin Reservoir. Once again the highway climbs rather steadily for three and one-half miles, passing the Shutesbury road (31.0) on the right, until it reaches another lookout (34.6) from which the trenched New England upland spreads out to the east. Pelham gneiss is the main rock on the broad ridge west of the Quabbin basin, especially in the vicinity of Pelham (35.2), which gave the rock its name. The tour turns east to Amherst (41.7), following a section which has been described elsewhere (see pp. 78-79). The principal sights include the panorama of the Connecticut Lowland and the ice-margin lake deposits. The drive from Amherst to Northampton (see pp. 78-79) and from Northampton to South Deerfield (see pp. 87-88) on Federal Highway 5 has likewise been covered in other tours, but some new features may be seen along the shorter route from Amherst to Sunderland. The Sunderland road turns right at the north end of the Amherst common. It descends, first, from Amherst Island, in glacial Lake Hadley, to the old beach at Massachusetts State College (42.6), and then from the beach to the lake bottom (43.2) north of the campus. The route takes the left fork in North Amherst (44.2), traverses part of the old lake bed, swings west around the Long Plain delta (45.5), and crosses its entrenched brook (46.1). Most of the stream’s water seeps through the delta sands and gravels, and emerges in springs at the Fish Hatchery (46.3). Gravel pits across the road furnish an excellent section of the fore-set and top-set beds of the delta. The road right (46.8) goes to the delta top east of Mount Toby, Montague and Turners Falls, but the main highway continues north.
